Channel Resource Prioritization for 5G NR Handover Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The LTM switching mechanism in 5G NR systems experiences communication collisions or conflicts due to resource overlapping on channel resources, affecting overall system performance, particularly in scenarios with low delay and heavy traffic like extended reality (XR) and cloud game (CG) services.
Innovation Solution
A communication method and apparatus that determine channel resources based on priority rules to manage overlapping resources, ensuring that terminal devices prioritize high-priority information transmission and reception, thereby minimizing parallel sending and receiving conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If LTM switching mechanism is implemented to reduce cell handover delay, then handover speed is improved, but communication collisions occur on overlapping channel resources
Solution Approach 1:
The patent converts the harmful communication collisions into beneficial prioritization mechanisms by introducing priority rules that determine which channel resources to use when overlaps occur. The harmful overlapping resources are transformed into a decision-making framework that selects optimal resources based on priority levels, thereby eliminating collisions while maintaining fast handover capability.
Solution Approach 2:
The patent changes the parameter of resource selection by introducing priority levels (first priority, second priority, third priority) for different channel resources. This parameter change enables the terminal device to make informed decisions about which resources to use during handover, converting the resource overlap problem into a controlled selection process that prevents communication collisions.
2Productivity
If multiple channel resources are used simultaneously for serving cell and candidate cell, then communication capacity is improved, but resource overlapping causes conflicts
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different channel resources based on their specific characteristics and roles. Not all resources are treated equally - the patent identifies which resources should have higher priority (first priority) and which should have lower priority (second or third priority), allowing simultaneous use of multiple resources while preventing conflicts through localized prioritization.
3Productivity
If terminal device performs uplink sending and downlink receiving on overlapping resources, then communication efficiency is improved, but parallel processing conflicts occur
Solution Approach 1:
The patent introduces dynamic resource selection based on priority rules that can adapt to different communication scenarios. The terminal device dynamically determines which resources to use for uplink sending and downlink receiving based on the priority levels assigned to different channel resources, allowing efficient parallel processing while managing complexity through predefined priority guidelines.

AI summary
A communication method and apparatus are provided, and relate to the field of communication technologies. The method may include: determining a first channel resource and at least one second channel resource, where the first channel resource is used to receive and/or send first information, and the second channel resource is used to receive and/or send second information; and when resource overlapping exists between the first channel resource and the at least one second channel resource, according to a priority rule, receiving and/or sending the first information on the first channel resource, or receiving and/or sending the second information on the at least one second channel resource.
